osgEarth/Controls is missing

I'm trying to use vcpkg to compile the simdissdk
https://github.com/USNavalResearchLaboratory/simdissdk

Environment

• OS: [Windows]
• Compiler: MSVC 2022

To Reproduce
Steps to reproduce the behavior:

1. ./vcpkg install osgearth[core,blend2d,tools] --recurse
2. go to dir vcpkg\installed\x64-windows\include\osgEarth,
   the file Controls is missing
3. if copy vcpkg\buildtrees\osgearth\src\gearth-3.7-856020e42d.clean\src\osgEarth\Controls
   to vcpkg\installed\x64-windows\include\osgEarth
   the source code will compile,
   but the link will fail with this kind of error

无法解析的外部符号 "__declspec(dllimport) public: __cdecl osgEarth::Util::Controls::ControlNode::ControlNode(class osgEarth::Util::Controls::Control *,float)" (__imp_??0ControlNode@Controls@Util@osgEarth@@QEAA@PEAVControl@123@M@Z)，函数 "public: bool __cdecl simVis::View::addSceneControl(class osgEarth::Util::Controls::Control *,class osgEarth::GeoPoint const &,float)" (?addSceneControl@View@simVis@@QEAA_NPEAVControl@Controls@Util@osgEarth@@AEBVGeoPoint@6@M@Z) 中引用了该符号

Expected behavior
the code will compile and link happily
